This Head of Household competition is called "Code Breaker", and here’s how it works:

In this competition, each of you will need to solve 3 different codes. A 3 digit code, a 4 digit code and a 5 digit code.

Each of these codes contains numbers 1-9, and numbers are NOT repeated in each code.

Your aim is to solve all 3 codes in the least amount of guesses total.

After you guess all 3, your total guesses used will be added together to give a total, and the houseguest with the lowest total of guesses will become the new Head of Household.

This is a competition intended to be played on Skype, so reach out whenever you want to play.

Should there be a tie, whoever took the least amount of guesses on the 5 digit code would win. If that is even, then whoever took the least amount of guesses on the 4 digit code wins. If it is the same on all 3 codes then whoever took the least total time from their first 3 digit guess to their last 5 digit guess would win.

Any questions please ask on Skype prior to you competing.
